We live at a time when the Internet is used increasingly for communication, for information, and for the exchange of goods and services. Questions arise about how people with learning disabilities make use of this new technology. In this article, Bjorn Harrysson, with two of his colleagues, A. Svensk and G. I. Johansson, from the Department of Design Sciences at the Lund Institute of Technology in Sweden, explores the opportunities and difficulties experienced by members of this group when navigating the Internet.
Harrysson, Svensk and Johansson observed seven people, aged between 15 and 44 and with mild to moderate developmental disabilities, as they navigated between different web pages using the general tools of Microsoft Internet Explorer Web Browser. The authors describe some of the strategies that were used for moving within and between web pages and for opening web pages, carrying out searches and finding preferred web sites.
The results of the study are partly optimistic. The people involved made good use of many of the features of the general software. They experienced greater difficulties when it became necessary to use text to navigate and explore the huge potential of the Internet. Harrysson, Svensk and Johansson close their article by making a series of recommendations for developments that would facilitate ease of access and independence in the use of the Internet for people with developmental disabilities. 相似文献

In this study, methods for data acquisition, analysis, modelling, and simulation of performance parameters in road cycling on real tracks were developed and evaluated. A simulator was designed to facilitate the measurement in a laboratory environment. The simulation included real height profiles and a video playback that was synchronised with the cyclist’s current virtual position on the track, and online visualisation of course and performance parameters. Field data obtained on mountain tracks in this study were compared with the state-of-the-art mathematical model for road cycling power, established by Martin et al. (J Appl Biomech 14: 276–291, 1998), which accounts for the gradient force, air resistance, rolling resistance, frictional losses in wheel bearings and inertia. The model described the performance parameters accurately with correlation coefficients of 0.96–0.99 and signal-to-noise ratios of 19.7–23.9 dB. It was shown that the mathematical model could be implemented on an ergometer for simulating rides on real courses, providing similar quality measures when comparing field and simulator measurements. 相似文献

This paper investigates the content of the editorial commentary in the Melbourne-based commercial Italian-language newspaper Il Globo from 1979 to 1989 and argues that throughout the period under examination it consistently maintained a proactive role for, and on behalf of, the Italo-Australian community. A longitudinal study on selected editorials written by then editor-in-chief Nino Randazzo shows that the newspaper lobbied relevant authorities and Australian governments alike on issues that mattered most to the Italian community, especially those related to domestic politics, migrant settlement and immigration. Using a content analysis methodology, the editorials were categorised into commonly emerging themes, highlighting the extent to which the newspaper commented on issues that affected the rapidly changing Italo-Australian community which experienced an important demographic shift from being predominantly Italian-born to increasingly Australian-born. 相似文献

With a point of departure in the concept of democracy, this article aims to show how Swedish Popular Adult Education influenced the content of the established school system in Sweden. The Popular Adult Education and established school systems are studied through their relation to democracy, based on curricula, as well as on visionary and political steering documents. In accordance with conceptual history, the study shows how Popular Adult Education and the established school, with their different spaces of experience and references to separate traditions, gradually became accommodated through a common horizon of expectations about the importance of democracy. When this coalescence appeared, an administrative shift could be identified and the Popular Adult Education Movement was partially disarmed. 相似文献

Based on Self-Determination-Theory, Group-Effectiveness-Theory, and Cognitive-Network Theory a multi-level model is developed that explains two research questions. First, how can management motivate individuals to generate novel ideas? Second, how should management organize groups in order to facilitate creativity and implement radical innovations? From Self-Determination-Theory, propositions for the design of a reward system are derived. Arguments from Group-Effectiveness-Theory lead to the conclusion that permanent work groups with low social cohesion should emphasize idea generation, while cross-functional project teams with high social cohesion are best suited for radical innovation implementation. Effective group behavior modes for each kind of group and management practices for producing these modes are described based on Cognitive-Network-Theory. Implications of the model with regard to innovation management in different cultural settings and to group composition are discussed. 相似文献

AbstractWe aimed to illustrate support leg dynamics during instep kicking to evaluate the role of the support leg action in performance. Twelve male soccer players performed maximal instep kicks. Their motions and ground reaction forces were recorded by a motion capture system and a force platform. Moments and angular velocities of the support leg and pelvis were computed using inverse dynamics. In most joints of the support leg, the moments were not associated with or counteracting the joint motions except for the knee joint. It can be interpreted that the initial knee flexion motion counteracting the extension joint moment has a role to attenuate the shock of landing and the following knee extension motion associated with the extension joint moment indirectly contributes to accelerate the swing of kicking leg. Also, appreciable horizontal rotation of the pelvis coincided with increase of the interaction moment due to the hip joint reaction force on the support leg side. It can be assumed that the interaction moment was the main factor causing the pelvis counter-clockwise rotation within the horizontal plane from the overhead view that precedes a proximal-to-distal sequence of segmental action of the swing leg. 相似文献

Interactive and non-interactive pictures in multimedia learning environments: Effects on learning outcomes and learning efficiency 总被引：2，自引：2，他引：0
New technologies enable flexible combinations of text and interactive or non-interactive pictures. The aim of the present study was to investigate (a) whether adding pictures to texts is generally beneficial for learning or whether it can also have detrimental effects, (b) how interactivity of pictures affects learning, (c) whether the visualization format of pictures affects the structure of the learner's mental model, and (d) whether the visualization format modifies the effects of interactivity. One hundred university students were randomly assigned to five groups. In four groups, a text about the different daytimes and days on the earth was combined with interactive or non-interactive pictures of different visualization formats. In the fifth group, the text was presented without pictures. According to the results, adding pictures to text was neither beneficial nor harmful for learning. In terms of learning efficiency, however, learning from text only was more successful than learning from text and pictures. Interactivity was beneficial for one learning task, but not for the other task. The visualization format affected participants’ interaction with pictures, but not the learning outcomes; however this effect was not influenced by interactivity. Implications for multimedia design and for further research are pointed out. 相似文献
